    4. Examine this program and anticipate the output: 

1: #include <iostream.h>
2: int main()
3: {
4: int a = 1, b = 1, c;
5: if (c = (a-b))
6: cout << "The value of c is: " << c;
7: return 0;
8: }

On line 5 the truth test for the if statement is supposed to be a comparison,
but a single = is there, making it an assignment to c of the value of a-b, which
means it will always be true unless a - b equals 0
